The first week of rehab for Tripp Halstead was at times encouraging and stressful, his parents said.

The Winder toddler injured about a month ago by a tree limb that fell on his head after the winds of Hurricane Sandy swept through his Barrow County daycare, is entering his second week at Children's Healthcare of Atlanta at Scottish Rite.

On Tuesday afternoon, his mother, Stacy, wrote on Facebook that her son had a "rollercoaster" night on Monday, and had a rehab session cancelled on Tuesday because his temperature spiked, and he had a CAT scan and blood work done.

Halstead, 2, had casts removed from his feet, and will have to wear splints every two hours, but the casts are scheduled to return on Wednesday.

"Every test came back fine," Stacy wrote. "We assume he just worked himself up to a fever with all the crying and hating the casts."

While Halstead has slept through some rehab sessions, Stacy wrote that he was awake for one on Tuesday afternoon.

"They were so right with the roller coaster theme," she wrote. "Yesterday, a good day, then horrible night, then a scary morning and now a nice afternoon!! Just a tad stressful being here."

On Tuesday morning, Halstead's father, Bill, wrote that his son made strides at a Monday rehab session. Halstead pushed a button to play music, and looked at the source of a sound from a train or dog.

Also on Monday, Halstead had red casts put on his feet, and his parents chose red to match their son's favorite movie character, Lightning McQueen, from the "Cars" movies.

"I feel bad for him," Stacy wrote. "I know they have to be very uncomfortable, but they are necessary if he is ever going to be able to walk again."

Halstead swallowed some water on Monday, and held his head for a few moments. On Sunday, the rehab focused on motor skills.

On Monday, Wing Slingers Grill in Hoschton and Atlanta-area Chili's locations donated a percentage of sales.

On Saturday, Kidz Klips in Buford will have a fundraiser from 9 a.m. to 5 p.m. Also in Buford, the Norwood Insurance Agency has pledged $1,000 toward Halstead's medical expenses, and will give an additional $10 for each insurance review or quote in Georgia, South Carolina, Tennessee and Alabama, up to $2,000.

Georgia Spa Company stores in Athens, Buford and Kennesaw will hold a raffle for a hot tub or Big Green Egg grill on Dec. 14. Tickets are available at each store and the Community Bank and Trust in Winder. The company is donating 100 percent of the proceeds to the family. The drawing will be Dec. 14 and 2,000 tickets, which cost $10 each, will be sold.
